Come out with energy and mingle (6)
I believe the answer is:
emerge
'come out' is the definition.
(synonyms)
'energy and mingle' is the wordplay.
'energy' becomes 'e' (physics symbol as in E=mce).
'and' is a charade indicator (letters next to each other).
'mingle' becomes 'merge' (I can't justify this - if you can you should believe this answer much more).
'e'+'merge'='EMERGE'
'with' is the link.
Can you help me to learn more?
(Other definitions for emerge that I've seen before include "Materialize" , "Come into view" , "Suddenly appear" , "Come to light" , "Break out (from an egg)" .)
